Adding even more to the magnitude of their Audi 8Y RS3 ECU tuning, Unitronic is proud to introduce its Advanced Features. Thanks to the proprietary ECU code, the Unitronic Advanced Features (UAF) Add-On gives unparalleled levels of control for true adjustability directly from the driver’s seat.
Let’s face it, one of the challenges often faced during development is making decisions on subjective subjects like Exhaust Overrun (the infamous pops and bangs) or subjects with an element of variability in nature, like Launch Control RPM Setpoint. UAF solves these issues with introducing adjustability controlled through the cruise control stalk in coordination with the visual paged menu system using the power and torque gauges on the virtual cockpit instrument cluster.
To enter the UAF menu, first engage the parking brake and place your foot firmly on the brake pedal. Ensure you can see the Power and Torque gauges on the virtual cockpit instrument cluster. Press and hold the CRUISE CONTROL SET button for 3 seconds. The Power (PWR) and Torque (TQ) Gauges will both begin to display 1. The Power (PWR) Gauge corresponds to the page in the menu and the Torque (TQ) gauge corresponds to the index value selected.
Use the CRUISE CONTROL UP & DOWN buttons to toggle through pages and use the CRUISE CONTROL RESUME & CANCEL buttons to toggle between selected index values.
To save the values, release your foot off of the brake pedal. Be sure to disengage the parking brake before driving off or trying to engage launch control.
For example, to adjust the ADJUSTABLE LAUNCH CONTROL (ALC) from 4000RPM to 5000RPM, first ensure the parking brake is engaged and your foot is firmly pressed on the brake pedal. Press and hold the CRUISE CONTROL SET button and wait for PWR 1 / TQ 1 to display. Press CRUISE CONTROL UP 2 times to PWR 3. Press CRUISE CONTROL RESUME 5 times TQ 6. You will also see the RPM gauge fill with red to the indicated RPM Setpoint. Release the brake pedal to save the settings. Don’t forget to disengage the parking brake before driving off or trying to engage launch control.
While Unitronic will continue to introduce new Advanced Features over time, the initial offerings will include:
Exhaust Overrun (Pops and Bangs)
- Adjustable Drive Mode based PnB (Enabled in Dynamic & Performance modes)
- 3 levels of duration (Off, Short, Long)
- 3 levels of intensity (Low, Medium, High)
PWR 1:
- TQ 1 = PNB DURATION - ALWAYS OFF
- TQ 2 = PNB DURATION - SHORT / ACTIVE DYNAMIC & PERFORMANCE
- TQ 3 = PNB DURATION - LONG / ACTIVE DYNAMIC & PERFORMANCE
PWR 2:
- TQ 1 = PNB INTENSITY - LOW
- TQ 2 = PNB INTENSITY - MEDIUM
- TQ 3 = PNB INTENSITY - HIGH
Adjustable Launch Control
- 8 Adjustable RPM Setpoints (4000-5400)
- 3 adjustable boost levels (Low, Medium, High)
PWR 3:
- TQ1 = LAUNCH CONTROL 4000 RPM (STOCK)
- TQ2 = LAUNCH CONTROL 4200 RPM
- TQ3 = LAUNCH CONTROL 4400 RPM
- TQ4 = LAUNCH CONTROL 4600 RPM
- TQ5 = LAUNCH CONTROL 4800 RPM
- TQ6 = LAUNCH CONTROL 5000 RPM
- TQ7 = LAUNCH CONTROL 5200 RPM
- TQ8 = LAUNCH CONTROL 5400 RPM
RPM GAUGE MOVES TO SETPOINT WITH EACH INCREMENT
PWR 4:
- TQ1 = LAUNCH BOOST - LOW
- TQ2 = LAUNCH BOOST - MEDIUM
- TQ3 = LAUNCH BOOST - HIGH
BOOST GAUGE ON VIRTUAL COCKPIT MOVES TO SETPOINT WITH EACH INCREMENT
Rolling Launch Control
- User adjustable RPM setpoint

Unitronic also built in plenty of failsafes and safety mechanisms into its Advanced Features to protect the engine and its components as much as possible. Certain preconditions apply to function activation or engagement, and other criteria control inhibition of functions.
PNB Preconditions:
- Minimum Engine Speed = 2500 rpm
- Minimum Coolant Temp. = 50°C / 122°F
- Minimum Oil Temp. = 30°C / 86°F
- Maximum EGT = 950°C / 1742°F
- Drive Select Mode (DrvMod) = Dynamic, Performance, or selecting S-mode from any DrvMod
ALC Preconditions:
- Drive Select Mode (DrvMod) = Dynamic, Performance, or selecting S-mode from any DrvMod
- Minimum Brake Pedal Pressure = 1.5 MPa / 217.5 psi
- Minimum Accelerator Pedal = 90%
- Maximum Catalyst Temp. = 885°C
- Coolant Temp. Range = 60°C to 110°C
RLC Preconditions:
- Cruise Control = OFF
- Minimum Coolant Temp. = 75°C / 167°F
- Minimum Oil Temp. = 70°C / 158°F
- Maximum EGT = 900°C / 1652°F
- Minimum Vehicle Speed = 50 kph / 32 mph
- Minimum Engine Speed = 3000 rpm
- Minimum Accelerator Pedal = 85%
- Drive Select Mode (DrvMod) = Dynamic or Performance + Manual (TT/Tip) Mode
- RLC Max Activation Time = 5 sec
- RLC Re-Activation Delay = 15 sec
Diagnostic Feedback:
If any preconditions are not met, the Power Gauge will show 11 and the Torque Gauge will display a single numerical value, which corresponds to the unmet precondition:
- 2 = Min. Engine Speed Not Reached
- 3 = Min. Vehicle Speed Not Reached
- 4 = Min. Coolant Temperature Not Reached
- 5 = Min. Oil Temperature Not Reached
- 6 = Maximum EGT Exceeded
- 7 = Wrong Drive Mode
- 8 = Gearbox Not in Manual (TT/TIP) Mode
